A Japanese dentist, of all people, has invented a sculpted pot that will automatically stir its contents as they heat up. It promises to completely revolutionize cooking, at least for the world's laziest chefs.

The Kuru-Kuru Nabe (aka the 'Pot Round and Round') was invented by Hideki Watanabe, who came up with the design after experimenting with dental plaster at his practice. The pot relies on thermodynamics to create a whirlpool motion as liquids heat up. It not only saves you from having to stir, but it allows for a more efficient and even heating process, and has the added benefit of compacting foam so the pot is less likely to boil over.

It's certainly not going to work for particularly thick recipes, like say a pot of chili, but for soups and such it seems downright genius. So we sincerely hope Watanabe finds an investor or two to help put this into production. [Watanabe via InventorSpot]
